Patent JP-H03209588-A (JP)
Title: Optical character reader
Inventor: SENZAKI TAKUSHI
IPC: G06K9/34
Filed: 1990-01-11
Abstract: PURPOSE:To extract an independent block, where characters linked by a real underline exist by outputting an underline presence / absence information and an underline occupying area information based on a character string picture and removing an underline occupying area included in the character string picture based on those both information. CONSTITUTION:An underline detection circuit 22 executes projection in two longitudinal and lateral directions to one part such as a tip or a rear end determined in advance concerning character string picture information D10 and outputs presence / absence information I1 concerning the existence of the underline and underline occupying area information I2 as underline information I. A character string picture correcting circuit 23 outputs corrected character string picture information D20 deleting the underline occupying area based on the underline information I outputted from the underline detecting circuit 22 in respect to the character string picture information D10 outputted from a character string picture extracting circuit 21. An independent block extracting circuit 24 executes projection to the corrected character string picture information D20 in the two longitudinal and lateral directions and outputs respective characters as independent block extracting picture information D30. Thus, even when the underline composed of the real line or a broken line gets contact with a handwritten character, the character can be segmented for each character.
